Automatically Updating the Date and Time
The date and time for the set time zones (pp. 19, 181) will be automatically
updated when the camera receives a GPS satellite signal.
How do I check if the time was automatically updated?
[Update completed] will display in the Date/Time screen in Step 3 on p. 21 if the
date and time were automatically updated. Additionally, [Time Update: On] will
appear if the signal has not yet been received from a GPS satellite.
If [Time Update] is set to [On], the date/time will automatically update, and
you cannot change the date and time even by displaying the Date/Time
screen using the steps on p. 21.
Set [GPS] to [On].
Follow Steps 1 and 2 on p. 111 to change
the setting.
Choose a setting.
Press the op buttons or turn the 7 dial
to choose [Time Update], then press the
qr buttons to choose [On].
